Title: Process for aggregating difficult to aggregate particles and the product thereof
IPC: A23P1/02
Filed: 1963-04-17
Abstract: A process of aggregating a particulate difficult-to-aggregate material comprises mixing the difficult-to-aggregate particles with a particulate amorphous aggregating agent to form a mixture containing from 5 to 50% of the aggregating agent, the aggregating agent being anhydrous lactose, anhydrous whey or "modified" anhydrous whey, aggregating the mixture by subjecting it to a high velocity flow of hot air to increase the total moisture content of the mixture by 2 to 6% based on the dry weight of the mixture before being subjected to the high velocity air flow, thus causing the difficultto-aggregate particles to adhere to the aggregating agent to form aggregates, and then drying the aggregates to prevent crystallization of the amorphous aggregating agent.  The term "modified" anhydrous whey refers to whey from which the salty taste has been eliminated. The particulate difficult-to-aggregate materials may be foods and numerous chemical and biological materials, including dried glues, enzymes, fertilizers, pesticides, herbicides and other finely divided powder substances, and numerous dried pharmaceutical products. Under preferred operating conditions, the mixture is subjected to a high velocity air flow at a temperature of from 125 DEG  to 185 DEG  F. for from 2 to 8 seconds, the aggregates thus formed are dried in air at temperatures ranging from 200 DEG  to 325 DEG  F., and the total amount of time for subjecting the mixture to the high velocity air flow and for drying the aggregates is from 5 to 20 seconds.  The dried aggregated product is passed along a shaker table to sizing rolls prior to packaging.  Examples disclose the aggregation of (1) a mixture consisting of 8 parts spray dried egg albumen and 2 parts spray dried anhydrous lactose, (2) a mixture consisting of 8 parts spray dried egg yolk and 2 parts of the anhydrous lactose, and (3) a mixture consisting of 8 parts spray dried whole egg and 2 parts of the anhydrous lactose.ALSO:A process of aggregating a particulate difficult-to-aggregate material comprises mixing the difficult-to-aggregate particles with a particulate amorphous aggregating agent to form a mixture containing from 5 to 50% of the aggregating agent, the aggregating agent being anhydrous lactose, anhydrous whey or "modified" anhydrous whey, aggregating the mixture by subjecting it to a high velocity flow of hot air to increase the total moisture content of the mixture by 2 to 6% based on the dry weight of the mixture before being subjected to the high velocity air flow, thus causing the difficult-to-aggregate particles to adhere to the aggregating agent to form aggregates, and then drying the aggregates to prevent crystallisation of the amorphous aggregating agent.
